Karasev, M. Over a long period of time only necrosis was considered to be a mechanism of myocardial cell death occurring due to various pathological states.
In the recent years much more attention has been paid to apoptosis of cardiomyocytes for it may also be one of pathogenetic factors contributing to the development of heart failure, as it was hypothesized by a number of authors. In particular, it was shown that apoptosis rate significantly increased in the myocardium under chronic hemodinamic overload.
But there is still very little data concerning the effect of acute cardiac overload on programmed cardiomyocyte death and myocardial structure. The experiment was performed on 20 male Chinchilla rabbits weighing Acute overload of the left ventricle LV was induced in narcotized animals by aortic narrowing with the use of metal spiral. The control group comprised intact rabbits.
Morphological study of the LV was carried out by light microscopy of semi-thin sections.

Cardiomyocyte apoptosis was investigated by morphological and immunihistohemical TUNEL-assay methods. It was found that the left ventricular myocardium underwent profound morphological changes mainly characterized by severe tissue damage: on day 1 the area of destruction sites was 13,4 times as much as in the controls and then remained at nearly the same level.
There was also a considerable expansion of extracellular space which is evidence of tissue oedema. According to fogyni, leállítva a mirtazapin data, there was a progressive increase in apoptotic index in the left ventricular myocardium as the pathological process developed.
Immunohistochemical tests revealed a significant rise of TUNEL-positive cardiomyocytes at all investigated terms with peak value on day 3. Thus, in acute cardiac overload caused by aortal stenosis the number of viable cardiomyocytes of the LV may be reduced both due to cell injury and also owing to apoptotic death involvement. Supervisor s : Blagonravov M. A common denominator underlying maladies of the geriatric population, is aging itself. It is likely that both environmental and genetic factors dictate the rate of aging process; much has been done in rob sonic fogyás those belonging in the former tier, but little is known about those that comprise the latter.
Mitochondrial dysfunction has been implicated in aging. Mitochondrial functions rely exclusively on compartmentalization, demanding an intact inner membrane for the development of membrane potential. However, upon stressful stimuli, mitochondria form a pore across the two membranes, by recruiting intrinsic proteins. The expression of all other aging markers exhibited no statistically significant difference.
Our results are combined with those obtained by different approaches, in which the very same mice have been evaluated for behavioral alterations, while the brains of other mice are being evaluated for region-specific alterations in the expression of aging markers by immunocytochemistry. The results rob sonic fogyás from the overall work may provide valuable information in terms of pinpointing cyclophilin D as a target for an aging-combating drug.

Effect of knocking out cyclophilin D on region-specific distribution of mGlur1 and GFAP expression in the mouse brain Lilla Kepes, Semmelweis University Faculty rob sonic fogyás Medicine 4th 95 kg fogyni Effects of whole body cryotherapy on chosen parameters of cardiovascular system Lukac Stefan, Comenius University Faculty of Medicine 2nd year [email protected] Genetic proof that the mitochondrial protein cyclophilin D cypD plays a major role in the manifestation of necrotic cell death was established by using genetically engineered cypD knock out mice.
However, mGluR1 expression exhibited a significantly different pattern of expression in brain regions among the three groups, a finding that could not have been yielded from western blotting alone. These results will be cross-correlated by those obtained by evaluating behavioral alterations from the same mice prior to the processing of their brains.
These efforts may provide valuable information in rob sonic fogyás of pinpointing cyclophilin D as a target for an rob sonic fogyás drug.

Supervisor s : Christos Chinopoulos, Adjunct Professor, Department of Medical Biochemistry, Semmelweis University Whole body cryotherapy WBCT is a supporting therapeutic method that uses application of extremely low temperatures — °C— °C and its surface stimulating effects on the human body.
It is used mainly for treatment of musculoskeletal injuries, skin diseases or multiple sclerosis. Our work was focused on cryotherapy-caused effects in hemodynamic parameters as a risk factor for patients undergoing treatment by cold. We studied gender and age differences.
No proband suffered from any cardiovascular disease, nor used any medication affecting BP and PF. Significant increase in systolic BP was found in both groups p 0. RI represents myocardial oxygen consumption and load on cardiovascular system. Fogyni harcok statistical significance was observable only in females older than 40 years. We can conclude that WBCT causes an increase in both systolic and diastolic BP, decrease PF regardless of both gender and age and does not cause any significant change in oxygen consumption by myocardium.
Thus we could recommend WBCT as the safe method for the regeneration rob sonic fogyás healthy subjects without persisted cardiovascular rob sonic fogyás. Lukáè Š. Haemodynamic response of cardiovascular system on whole—body cryotherapy.

Expression of a-SMA in hepatic stellate cells as their activation biomarker with down-regulated immune response in human hydatid infection Ali Vatankhah, Semmelweis University Faculty of Medicine — József Tímár, Semmelweis University 2nd Department of Pathology [email protected] ; [email protected] Fibrosis is one of the most important pathological manifestations of chronic hydatid infection CHI.
Inflammatory response induces proliferation and migration of macrophages that in turn generate stimulatory signals for hepatic stellate cells HSCs activation.

This process has an essential role in tissue fibrosis during chronic liver injuries and can be characterized by expression of cytoplasmic smooth muscle actin-alpha a-SMA. In vitro studies along with animal experiments have indicated that hydatid cyst antigens may induce down-regulated Th1-like immunity as well as suppressed macrophage activation; however it rob sonic fogyás still unclear whether how the fibrotic tissue can be formed around the hydatid lesion in the course of chronic infection.
We believe yet rob sonic fogyás has been no In Situ study on human CHI which could show the orchestration of inflammatory infiltrate and contribution of HSCs in parasite-induced liver fibrosis.
Eosinophilia was assessed in hematoxilin-eosine stained tissue sections. Results achieved by this study could suggest that CHI in human liver may induce activation and trans-differentiation of HSCs which are underlying mechanisms for initiation tissue fibrosis; nonetheless the host-parasite immune interactions evidently result in macrophage inhibitory immune profile.

Clin Exp Metastasis. Epub Feb Chronobiological study Monika Nováková — Milan Maretta, Pavol Jozef Šafárik University Faculty of Medicine 4th year [email protected] ; [email protected] For selecting appropriate anaesthesia intended for making experimental models under in vivo conditions is important to gathter cardiovascular data. The impact of selected anaethesia in relation to individual surgucal interventions on endogenous factors controlling circadian rhytm of the myocardial functions must be considered during selection of an anaesthetic.
Aim of the experiment was to compare reaction of cardiovascular system under different conditions on light and dark cycle LD. In the first phase the duration of the light period was from to h.
In the second phase the results were measured after inverse setting of the LD cycle. Animlas in both phases of experiment were subjected to several surgical rob sonic fogyás tracheotomy, preparation of femoral artery and thoracotomy after recording the data from spontaneus breathing intact animals. Our results showed that administration of pentobarbital anaesthesia has an impact on preservation of LD differences after surgical interventions considering significant differences in duration of PQ interval and in the amplitude of P wave after preparation of femoral artery.
Also significant differences were observed in duration of QT, QTc intervals and similarly in amplitude of P wave after thoracotomy. Due to fact, there were not observed any significant differences in each of measured parameter in spontaneus breating rats, we can proclaim, that pentobarbital anaesthesia probably eliminate the LD differences in individual electrophysiological parameters of ECG.

In: Physiological Research. In: Central European Journal of Medicine. Osteoclasts are the unique bone resorbing cells of hematopoietic origin. The phosphoinositide 3-kinases PI3K have crucial roles in regulating a variety of cellular functions including growth, proliferation, survival, metabolism, cytoskeletal functions, migration and general signal transduction, but their role in osteoclast biology is poorly understood.

Here we tested the role of the PI3Kb and PI3Kd isoforms in in vitro osteoclast development and function using a pharmacological approach. Vehicle control samples received 0. Osteoclast differentiation and function were examined by osteoclastspecific TRAP-staining and resorption of artificial hydroxyapatite surface.
Importantly, osteoclast development was nearly completely blocked by the combined pharmacological inhibition of both PI3Kb and PI3Kd.

The presence of TGX or IC significantly decreased the actin ring formation capacity of mature osteoclasts, while the combined pharmacological inhibition of both PI3Kb and PI3Kd led to the practically complete disappearance of actin ring-like rob sonic fogyás in the in vitro osteoclast rob sonic fogyás.
Our results indicate that PI3Kb and PI3Kd play a az azitromicin lefogy but overlapping role in osteoclast development and function likely by regulating the organization of the osteoclast cytoskeleton.
Introduction: Syphilis has been a persistent public health challenge for centuries and is now gaining renewed attention against the backdrop of the Rob sonic fogyás pandemic. Especially around andoutbreaks of syphilis have been observed rob sonic fogyás many countries around the world, especially among MSM. Social reasons facilitating more rapid and efficient transmission can be: Increasing use of internet to select sexual partners with the same HIV status Serosorting leading to more unprotected sex among HIV positive men, HIV treatment optimism leading to higher sexual risk taking behavior, increased transmission through oral sex, considered safer sex with respect to HIV risk, natural increases in the proportion of homosexually active male population, higher number of sexual partners among MSM.
Changes in the course of Syphilis, when HIV is accompanied to the disease have also been observed. Multiple chancres in primary syphilis and multiple genital ulcers in secondary syphilis, increased frequency of acute syphilitic meningitis in early syphilis, high RPR titers, predilection of Jarisch-Herxheimer reaction, delayed or failed normalization of CSF markers after treatment are just a few examples. We have no former publications.
